TO ALL WHOM ITMAY CONCERN:

Be it known that we,'\VILL'I1li\I \V. HUGHES and JAMES C, A DAMS ,-bothoF-Philadelphia, in the State oi Pennsylvania, have invented a new, and useful improvement in tlie-const'ruction of the iron Flooring of Malt Kilns; and wedo hereby declare the following to be a full and exact description of the same, reference beinghad to the annexed drawings, making a part of this specification, in which- Figure 1 represents a vieiv of malt-kiln floor seen from below. 'Figure 2, an end view corresponding to fig. 1;

Figure 3, a side view corresponding to fig. 1.

Figure 4, a detached plate of the floor. I

Heretofore the floors of malt kilnshave been supported, not directly upon thejoists, but upon bars placed about one foot apart. Our improvement consists in making the plates of perforated sheet iron of suflicient length to extend directly over and rest upon one or more of the main joists, A B, C D, or E. One of these plates is shown in fig. 4, flanged upon all sides. It is about onethirty-second of an inch thick, and isabont one inch deep, and is stiffened by an iron plate or bar, G H, extending longitudinally along the inside of each of the side flanges, and riveted or bolted securely to the longitudinal flanges. "These plates are alsostifi'ened by transverse bars or plates, J K, bent at each end, and "bolted or riveted to the plates andflanges. These transverse stays or braces J K. are placed about fourteen inches apart. The flooring plates are laid side by side upon the joists, and the contiguous plates are secured together by pins, Z Z Z, rivets, or bolts along their contiguous flanged edges G H. The plates rest upon the joists with the flanged edges downward, and are also secured to the joists by means of notched clips, on m, which fit upon the joist and have two holes for the insertion. of a wire to tie them to the joists. The advantage of a floor constructed in this way is, that it makes a rigid level floor and dispenses with upper bars.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. Constructing malt-kiln floors of perforated flanged plates extending over two or more joists, stiffened by the side bars or slips G H, and the transverse bars-0r strips J K, the flanges of said plates being also secured together by pins, bolts, or rivets passing through the contiguous flanges.

'2. We claim securing the flanged plates, constructed as above described, to the iron joists below by means of clips m m, and Wires or their equivalents.
